Rework-free plasma cuts through approved swirl gas technology
For over 50 years, Kjellberg Finsterwalde has been accomplishing pioneering work in development and
production of plasma cutting technologies. The development of the swirl gas technology was the result
of the objective target for achieving a nearly rework-free and cost-effective plasma cut. Plasma torches of
the FineFocus series are producing due to the Double-Straight-Effect high quality surfaces at both sides
of the cut, reducing so the costs for rework operations to a minimum.
Particular advantages of this technology are:
Cutting surface
Swirl gas
Plasma gas
Water inlet
Water outlet
Potential-free swirl gas nozzle guarantees a
constant cut quality over a long cutting period,
protecting the nozzle against upcoming hot material
Reliable stationary piercing up to 12 mm material
thickness
Perfect running piercing up to 25 mm in connection
with arc voltage depending height control
Short lead-in paths enable small circles and hole
cutting
Dross-free cutting of stainless steels with excellent
cutting quality
Increased life time of the tungsten electrode when
cutting stainless steels by reducing the nitrogen
content in the plasma gas, and increasing the
nitrogen content in the swirl gas
Cathodes
Screw cap
Enhanced longevity through XL-Life-Time System
When cutting mild steels with the plasma gas air some surface nitriting can occur. To avoid porosity during
welding this layer must be removed by expensive machining operations. The plasma gas oxgen prevents
this problem and avoids the cost-intensive rework.
With the XL-Life-System with dual-gas ignition
nozzles and cathodes were precisely adapted and
provide for longevity of the consumables.
In addition the following effective measures increase
the life of nozzles and cathodes and reduce the
operating costs considerably:
For cutting of three-dimensional parts
special torches are offered.
Direct and extreme effective liquid cooling around
the stress loaded area of the consumables
Soft-start-circuit for the cutting current
Process-optimized gas control during piercing
and at the cut end

Outstanding suitability for CNC controlled demands
The technical properties and the variety of peripheral components are recommending the FineFocus
450
especially for CNC controlled applications in a capacity range of 40 to 130 A. In particular the following
facts are remarkable:
Smooth cutting current and excellent
cutting quality ensured by 12-pulse
circuit
Nozzle saving, contactless high
voltage ignition of the pilot arc
Precise and reproducible adjustment
of the process data by adaptive units,
like plasma gas adjustment and
mixing devices
Fulfillment of highest safety standards
Select-Control-Function for setting
the cutting current
User-friendly and extensive diagnostic
and service system for the
supervision of all important operation

highest quality will not be required.
